APerez It would more likely be providing sheet music/chords plus instructions/tutorial on how to play the music, broken down into sections or possibly providing a much simplified version.
I think the teaching/tutorial area is a bit of a grey one because some say it falls under fair use, however publishing the music of a copyright would infringe on the music manuscript publisher, which is why in the past I've done it with things which are out of copyright/public domain.
I know when put up things on YouTube with a copyright strike, sometimes the rights holder allows you to continue to use the content but they take any ad revenue. I am not sure it's so clear cut on an independent website. They could argue I am profiting from publishing something I don't have the right to share. Or Google could drop my account for publishing copyright material.
Anyway, I have plenty of suggestions and my own editorial calendar which don't have any grey areas so plenty to be getting on with 🙂
